DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
[0022] Please refer to Figures 1-4 , the present application provides a technical solution: wire transfer RGV car for surface treatment, including suspension rail main body 1, suspension rail main body 1 is long strip steel structure, its top and the workshop pre-set load-bearing beam or support fixed connection, as the whole RGV car foundation bearing structure, used to fix the whole device in the workshop space. The suspension rail main body 1 is installed with the suspension rail trolley 2, the suspension rail trolley 2 can move along the extension direction of the suspension rail main body 1, realize the horizontal position adjustment of the whole transfer structure, provide horizontal movement basis for wire transfer. The bottom of the suspension rail trolley 2 is installed with the frame 3, the frame 3 is fixedly connected with the suspension rail trolley 2, provides support carrier for the subsequent installation of the chassis 5 and the lifting mechanism 4.
[0023] The bottom of the frame 3 is installed with the chassis 5. The bottom of the chassis 5 is symmetrically installed with the guide rail 6, which is used to guide the movement of the lifting frame 7. The lifting frame 7 is slidably connected to the guide rail 6, and can slide up and down along the vertical direction of the guide rail 6 to adjust its height. The lifting frame 7 is installed with a lifting hook 9 for lifting wire in the middle part, the lifting hook 9 is used for hanging wire, and bears the lifting weight of the wire. The inside of the frame 3 is installed with a lifting mechanism 4 for controlling the up and down movement of the lifting frame 7, the lifting mechanism 4 cooperates with the lifting frame 7, drives the lifting frame 7 to slide along the guide rail 6 through its own action, and then adjusts the height of the wire hanging on the lifting hook 9.
[0024] As shown in Figure 1 and Figure 2 : two pulleys 8 are symmetrically connected to the lifting frame 7, and the two pulleys 8 are connected to the lifting frame 7 through rotating shafts, and are symmetrically arranged to ensure balanced force. The outer circle of the two pulleys 8 is provided with an arc-shaped wheel groove matched with the steel wire rope, which matches the shape of the steel wire rope and is used to accommodate the steel wire rope to prevent the steel wire rope from being separated from the pulley 8 during transmission. At the same time, the sliding friction of the steel wire rope is converted into rolling friction through the rotation of the pulley 8, reducing the wear of the steel wire rope and improving the transmission efficiency.
[0025] As shown in Figure 1 and Figure 2As shown: the lifting mechanism 4 includes a wire drum 41; the two ends of the wire drum 41 are provided with circular limiting flapper to prevent the steel wire rope from falling off, and the circular limiting flapper is fixedly connected with the wire drum 41, which plays a limiting role on the steel wire rope wound outside the wire drum 41, avoiding the steel wire rope from sliding off the end of the wire drum 41 when winding or releasing. The outer side of the wire drum 41 is symmetrically wound with two groups of steel wire ropes, one end of the two groups of steel wire ropes is fixedly connected with the wire drum 41, and the other end is wound outside the two pulleys 8 respectively, the force direction of the steel wire rope is changed through the pulley 8, so that the two groups of steel wire ropes can synchronously exert pulling force or pushing force on the lifting frame 7, ensuring the force balance during the lifting process of the lifting frame 7, and preventing the lifting frame 7 from tilting.
[0026] As shown in Figure 1 and Figure 2 : the lifting mechanism 4 further includes a driving motor 42 and a wire fixing clamp 43; the driving motor 42 is installed outside the frame 3 to provide power output for the lifting mechanism 4. The output shaft of the driving motor 42 is connected with one end of the wire drum 41 through a speed reducer, and the speed reducer is a gear speed reducer or a worm gear speed reducer, the input end of which is connected with the output shaft of the driving motor 42 to receive the power output by the driving motor 42, and the output end is connected with the end of the wire drum 41 to transmit the power with increased torque to the wire drum 41 after speed reduction, so as to drive the wire drum 41 to rotate stably, ensuring the stability of the winding and releasing of the steel wire rope.
[0027] As shown in Figure 2 : the wire fixing clamp 43 is a U-shaped metal clamping piece with good structural strength. The wire fixing clamp 43 is installed on the lower surface of the frame 3. The wire fixing clamp 43 is fixedly connected with one end of the steel wire rope, and the position of the one end of the steel wire rope is fixed through the clamping action, so that the length of the steel wire rope can be adjusted with the wire fixing clamp 43 as the fixed end when the wire drum 41 rotates, and then the lifting frame 7 is stably pulled or pushed to move.
[0028] As shown in Figure 3 : the hook 9 is provided with a anti-falling protrusion 91 to prevent the wire from falling off, and the anti-falling protrusion 91 is integrally cast or welded with the hook 9. The anti-falling protrusion 91 is installed at the opening of the hook 9, forming a blocking structure at the opening position of the hook 9. When the wire is hung on the hook 9, the wire can be prevented from sliding off the opening of the hook 9, improving the safety during the wire transfer process.
[0029] As shown in Figure 1As shown: the frame body of the hanging rail trolley 2 adopts high-strength and corrosion-resistant materials, and can be selected from 1.4652 alloy, 725LN stainless steel or 3J01 elastic alloy. As the core bearing component of the hanging rail trolley 2, the frame body needs to bear the total weight of the frame 3, the chassis 5, the lifting mechanism 4 and the wire, and the high-strength material can ensure that the frame body is not easy to deform or damage during the bearing process. At the same time, there may be a corrosive environment in the surface treatment workshop, and the corrosion-resistant material can effectively improve the corrosion resistance of the frame body, prolong the service life of the hanging rail trolley 2, and ensure its long-term stable operation.
[0030] Working principle: the hanging rail main body 1 is fixed on the workshop bearing beam or support in advance as the fixed bearing basis of the whole device. When the transfer position needs to be adjusted, the hanging rail trolley 2 moves along the extension direction of the hanging rail main body 1, synchronously driving the frame 3, the chassis 5 and the subsequent components connected below to move as a whole, until the lifting hook 9 moves to the upper side of the wire to be transferred, completing the horizontal position calibration.
[0031] Start the driving motor 42, and the driving motor 42 drives the wire drum 41 to rotate. Since one end of the steel wire rope is clamped and fixed by the wire fixing clamp 43, the wire drum 41 releases the two groups of steel wire ropes wound thereon when rotating, and the steel wire ropes move along the outer side of the pulley 8, so that the lifting frame 7 vertically slides along the guide rails 6 on both sides of the chassis 5, thereby driving the lifting hook 9 in the middle of the lifting frame 7 to synchronously descend until the lifting hook 9 reaches the wire to be transferred. After the wire is hung on the lifting hook 9, the driving motor 42 switches the rotating direction, and the wire drum 41 starts to wind the two groups of steel wire ropes. In the winding process, the steel wire ropes exert an upward pulling force on the lifting frame 7, so that the lifting frame 7 vertically slides upward along the guide rails 6, and the lifting hook 9 synchronously rises with the wire. In this process, the anti-falling protrusion 91 on the lifting hook 9 blocks the wire from sliding out of the opening of the lifting hook 9, ensuring the stability of the wire hoisting.
[0032] After the wire rises to a safe height, the hanging rail trolley 2 moves along the hanging rail main body 1 again to transfer the wire to the target position required by the surface treatment process.
[0033] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
